anatomic evaluation of the left phrenic nerve relevant to epicardial and endocardial catheter ablation implications for phrenic nerve injury
Heart Rhythm, 2009Co-Authors: Damian Sanchezquintana, Vicente Climent, Siew Yen Ho, Margarita Murillo, Jose Angel CabreraAbstract:Background/Objective The purpose of this study was to clarify the spatial relationship between the left phrenic nerve (LPN) and key cardiac structures in order to minimize the risk of phrenic nerve injury during interventions. Methods The course and relationship of the LPN to various cardiac structures were examined by gross dissection and histologic sections of 22 human cadavers. Results The nerve descended on the Fibrous Pericardium along one of three courses: over the anterior surface of the left ventricle (18%), over the lateral margin of the left ventricle (59%), and in a posteroinferior direction (23%). The endocardium of the roof of the left atrial appendage was Conclusion During electrophysiologic interventions, the LPN is especially at risk when procedures are performed in the vicinity of the left atrial appendage and high left ventricular wall.

anatomic relations between the esophagus and left atrium and relevance for ablation of atrial fibrillation
Circulation, 2005Co-Authors: Damian Sanchezquintana, Jose Angel Cabrera, Vicente Climent, Jeronimo Farre, Maria Cristina De MendoncaAbstract:Background— Esophageal injury is a potential complication after intraoperative or percutaneous transcatheter ablation of the posterior aspect of the left atrium. Understanding the spatial relations between the esophagus and the left atrium is essential to reduce risks. Methods and Results— We examined by gross dissection the course of the esophagus in 15 cadavers. We measured the minimal distance of the esophageal wall to the endocardium of the left atrium with histological studies in 12 specimens. To measure the transmural thickness of the atrial wall, we sectioned another 30 human heart specimens in the sagittal plane at 3 different regions of the left atrium. The esophagus follows a variable course along the posterior aspect of the left atrium; its wall was <5 mm from the endocardium in 40% of specimens. The posterior left atrial wall has a variable thickness, being thickest adjacent to the coronary sinus and thinnest more superiorly. Behind is a layer of Fibrous Pericardium and fibrofatty tissue of ir...
